As shown in the figure, the screen golf system 10 using the surface light source is composed of a plurality of surface light source 100, a plurality of sensor system 200 and computer system 300.

A plurality of surface light source 100 is to diffuse and irradiate the light widely, one surface light source 100 is irradiated with a plurality of sensor system 200 at the same time to measure the golf ball (1) hit.

In one embodiment, the surface light source 100 includes a first surface light source 110 and a second surface light source 120, and the first surface light source 110 and the second surface light source 120 are spaced apart from each other by a predetermined distance. The light is emitted and irradiated.

The sensor system 200 also includes a first sensor system 210 and a second sensor system 220, and the first sensor system 210 and the second sensor system 220 are disposed to be spaced apart from each other by a predetermined distance. .

The first sensor system 210 and the second sensor system 220 may pass through a golf ball that is blocked by the light emitted from the first surface light source 110 and the second surface light source 120 or is blown out of the light. The transmitted light is sensed.

In other words, the first sensor system 210 and the second sensor system 220 receives the light emitted from the first surface light source 110 and the second surface light source 120, and is moved when the golf ball is hit. The light is blocked by the golf ball 1 or receives the transmitted light transmitted through the golf ball to sense the golf ball.

In this case, the first surface light source 110 and the second surface light source 120 irradiate light simultaneously to the first sensor system 210 and the second sensor system 220, respectively, and emit light emitted from the same surface light source. The first sensor system 210 and the second sensor system 220 can be operated to eliminate the need for a plurality of conventional light sources.

The sensed information of the first sensor system 210 and the second sensor system 220 is calculated by inferring the flight trajectory of the golf ball 1 by the computer system 300 having the trajectory estimation engine.

Of course, the computer system 300 includes installation position information including a separation distance between the first surface light source 110 and the second surface light source 120 and the separation between the first sensor system 210 and the second sensor system 220. It has installation position information including distance and arrangement information of the first surface light source 110, the second surface light source 120, the first sensor system 210, and the second sensor system 220.

Based on the positional information and the arrangement information, the trajectory estimation of the information sensed by the first surface light source 110, the second surface light source 120, the first sensor system 210, and the second sensor system 220 is performed. The flight trajectory of the golf ball hit by the engine is calculated.

Here, looking at the trajectory estimation engine of the computer system 300, the detection information of each of the golf balls in flight has the first detection information, the second detection information, the third detection information and the fourth detection information according to the embodiment. It includes.

First, the first detection information indicates the detection result of the first sensor system 210 for the first surface light source 110, and the second detection information indicates the second sensor system 220 for the first surface light source 110. The detection result of is shown.

The third detection information indicates the detection result of the first sensor system 210 for the second surface light source 120, and the fourth detection information indicates the second sensor system 220 for the second surface light source 120. The detection result is shown.

Each of the detection information is used to calculate the position of the hit golf ball (1), the first sensor system 210 and the second sensor system 220 to identify the two intersections (B1, B2).

As shown in FIGS. 2 to 3, first, the first intersection point B1 calculates the position of the golf ball 1 sensed by the first sensor system 210 using the first detection information and the third detection information. In addition, the second intersection point B2 calculates the position of the golf ball 1 sensed by the second sensor system 220 using the second detection information and the fourth detection information.

In order to identify the first intersection point B1 and the second intersection point B2, the positions of the first surface light source 110 and the second surface light source 120, the first sensor system 210, and the second sensor system ( Position of the 220, as well as the distance (S) of the light of the first surface light source 110 and the second surface light source 120 is blocked by the golf ball (1) or transmitted light transmitted through the golf ball (1) And the two end position (S1, S2) sensed, and the equation of the two straight lines intersected using the distance of the sensor system 210 at the first hitting point of the golf ball to check the intersection point using these two equations.

In other words, in order to confirm the first intersection point B1, the height Z of the first surface light source L1, the distance l of the first surface light source L1, and the second surface light source L2, The X axis distance g1 of the sensed first sensor system 210, the Y axis start position S1, the end position S2, and the distance S1 of the sensed first sensor system 210 are required,

The equation of a straight line connecting the first surface light source (L1) and the sensing end position (S2),

L1S2:

X = g1t, y = S2t, z = h-ht.

And the equation of a straight line connecting the second surface light source (L2) and the sensing start position (S1),

L2S1:

X = g1k, y = (S1-l) k + l, z = h-hk.

Accordingly, the first intersection point B1 is

Is confirmed.

In order to identify the second intersection point B2, the height Z of the first surface light source L1, the distance l of the first surface light source L1, and the second surface light source L2 are sensed. The X axis distance g2 of the second sensor system 220, the Y axis start position S3, the end position S4 and the distance Sl2 of the sensed second sensor system 220 are required,

The equation of a straight line connecting the first surface light source (L1) and the sensing end position (S4),

L1S4:

X = g2t, y = S4t, z = h-ht.

And the equation of a straight line connecting the second surface light source (L2) and the sensing start position (S3),

L2S3:

X = g2k, y = (S3-l) k + l, z = h-hk.

Accordingly, the second intersection point B2 is

Is confirmed.

The distance between the first intersection point B1 and the second intersection point B2 thus confirmed is

ego,

Y-axis start position S1 of the first sensor system 210, sensing time t1 of the end position S2, and Y-axis start position S3 of the second sensor system 220, and end position S4. After calculating the sensing time (t2),

The movement time Δt between the first crossing point B1 and the second crossing point B2 may be confirmed.

Δt = t2-t1

Accordingly, the moving speed between the first crossing point B1 and the second crossing point B2 of the golf ball is

이다.

to be.

On the other hand, as shown in Figures 4 to 5, the computer system 300 can set the tee position (B0) on which the first golf ball is placed, this tee position (B0) when the screen golf system is installed, The position is fixed and its height is set equal to the height of the sensor system 200.

The distance, angle, and time between the first crossing point B1 are checked at the tee position B0, and the horizontal angle, the declination angle, and the speed of the golf ball are calculated to determine the distance between the first crossing point B1 and the second crossing point B2. As the flight trajectory is calculated by comparing the horizontal angle, the declination angle and the speed, the hook and the slice of the golf ball can be checked.

In other words, if the tee position B0 can be checked, the flight trajectory of the hit golf ball can be calculated even by checking only the first crossing point B1 by the first sensor system 210.

At this time, the time from the tee position B0 to the first crossing point B1 is confirmed by measuring the hitting time of the golf ball. When the golf ball hits, the first hitting is provided with an acoustic sensor 700 that senses a hit sound. The position can be confirmed by measuring the time point t0 and comparing the hitting time point t0 with the time of the first crossing point B1.

In other words, the tee position (B0) can be confirmed as set at the time of initial installation, the golf ball hitting point at the tee position (B0) is measured by the acoustic sensor 700, the hit golf ball is the first sensor system By measuring the time to the first intersection point B1 measured by 210, the distance and the speed can be checked.

That is, the movement time Δt between the tee position B0 and the first intersection point B1 is

Δt = t1-t0

Accordingly, the moving speed between the tee position B0 and the first crossing point B1 of the golf ball is

이다.

to be.

By calculating the flight trajectory of the batting ball through the information of the tee position B0, the first crossing point B1, and the second crossing point B2, the slice of the golf ball and the change of the hook can be modeled. It is.

And two or more of the trajectory between the tee position B0 and the first intersection point B1, the trajectory between the first intersection point B1 and the second intersection point B2, and the trajectory between the tee position B0 and the second intersection point B2. If we use V to change the vertical angle without changing the horizontal angle, we can see that there is no slice or hook.

In addition, the trajectory estimation engine may additionally add an arbitrary wind speed and wind direction to the user, and may display flight trajectories by adding a deformation amount of the golf ball by the wind speed and wind direction.

This, in addition to the wind generated in the outdoor golf course, can be more easily adapted to the actual golf game can further improve the skills.

As such, the calculated information is calculated by calculating the flight angle, declination, and speed of the golf ball based on the distance, angle, and time between the first crossing point B1 and the second crossing point B2 in the computer system 300. do.

The flight trajectory can then be applied to a separate simulation, providing basic information about the distance and final arrival position, providing accurate data to the golfer.

At this time, when the position of the first surface light source 110 and the second surface light source 120 or the first sensor system 210 and the second sensor system 220 is reset, the position information and the degree of placement thereof are in real time. It is natural to be corrected.

In addition, the first surface light source 110 and the second surface light source 120 may be changed in various installation positions. The first surface light source 110 and the second surface light source 120 may be located at an outer upper portion of the first sensor system 210. The second sensor system 220 is irradiated with light at the same time.

In addition, other positions of the first surface light source 110 and the second surface light source 120 are positioned between the first sensor system 210 and the second sensor system 220 to be positioned above the first sensor system 210 and the second. Light may be irradiated to the sensor system 220 simultaneously.

In addition, the first surface light source 110 and the second surface light source 120 are positioned above the outer side of the second sensor system 220 to simultaneously irradiate light to the first sensor system 210 and the second sensor system 220. do.

Meanwhile, the first surface light source 110 and the second surface light source 120 may be installed at different positions, and the first surface light source 110 may be located at an outer upper portion of the first sensor system 210 and thus may be installed in the first surface light source 110. Light is irradiated to the sensor system 210 and the second sensor system 220 at the same time.
